The Utah State University Water Initiative has proposed to establish a Laboratory Watershed in the Bear River basin. The Bear River Range is the primary recharge area for the Bear Lake and Cache Valleys, two important sub-basins. The range exhibits snowmelt-dominated flow in the shallow soil or regolith zone, and deep bedrock groundwater flow, controlled by karst and fracture/fault zones. Carbonate rocks (limestone and dolostone) are abundant in the Bear River Range, and these rocks weather by dissolution, producing many sinkholes, caves and springs. As a result, much of the water in streams entering Bear Lake and Cache Valleys originates as springs in the Bear River Range. However, little is known about the flow paths, chemical evolution, and partitioning of the amounts of each component of flow in the system. Further, the locations of the recharge areas for these springs are largely unknown.
